Abstract

In an image recording device which records an image on a recording medium responsive to a desired gradation in each pixel and which includes a recording head for jetting an ink droplet having a diameter at a speed therefrom, the diameter of the ink droplet is modulated in response to the desired gradation in each pixel while the speed is modulated dependent on the modulated diameter. Thus, a position of impact of the ink droplet is not deviated, so that quality of image is not deteriorated.
